Datalogger Name and Sensor Warmup Time
To begin calibration and/or to change time interval settings, click the
Setup
button. A
Global Water
Setup
window will display.
If you want to change the datalogger name, click in the
Name
field and type in a new name.
In order to supply connected sensors with adequate power for accurate data measurments, set the
Sensor
Warmup Time
field to the specification indicated in your sensor manual. Note that this field should reflect
the sensor specification with the longest warm-up time. This setting dictates the length of time power is
applied to the attached sensors before the datalogger takes a reading.
For example, you set Global Logger* to a sensor warm-up time of 3 seconds, and to record readings every
20 minutes at fixed intervals. If the process begins at 12:02:00, power will be applied to attached sensors
immediately and readings taken at 12:02:03. At 12:22:00, power will again be applied to the attached sen-
sors, and the datalogger will take readings at 12:22:03. Note that if the recording interval fields are less
than or equal to the
Sensor Warmup Time
field, any attached sensors are powered continuously.
To change warm-up time, click in the
Sensor Warmup Time
field and enter the desired time (0 –15 sec-
onds). You may also click the up/down arrows to the right of the text field to increase or decrease the value
by 1.
